Because if you have no right to resist an unlawful police entry into your home (H/T Kevin), and all you can hear are guys banging on the door, yelling “Police! Open up!”, then how might you defend yourself?
If they’re legit police, raiding the wrong house through negligence (it happens all the time), then you’ve just made your situation far worse.
If they’re just a bunch of criminals dressed up like the police, then you’re in just as bad of a position.
From what I understand of the case itself, it looks like in this specific instance the police were okay to enter the man’s house and arrest him; however, this ruling seems to be far too sweeping.
